We opened the front gate of the Carter place and went slowly up the walk. Two ragged youngsters, alike even to freckles and squints, were playing in the yard.

“Is your mother around?” I asked.

“In the front room. Walk in,” they answered in identical tones.

As we got to the porch we heard voices, and stopped. I knocked, but the people within, engaged in animated, rather one-sided conversation, did not answer.

“‘In the front room. Walk in,’” quoted McKnight, and did so.

In the stuffy farm parlor two people were sitting. One, a pleasant-faced woman with a checked apron, rose, somewhat embarrassed, to meet us. She did not know me, and I was thankful. But our attention was riveted on a little man who was sitting before a table, writing busily. It was Hotchkiss!

He got up when he saw us, and had the grace to look uncomfortable.

“Such an interesting case,” he said nervously, “I took the liberty—”

“Look here,” said McKnight suddenly, “did you make any inquiries at the station?”

“A few,” he confessed. “I went to the theater last night—I felt the need of a little relaxation—and the sight of a picture there, a cinematograph affair, started a new line of thought. Probably the same clue brought you gentlemen. I learned a good bit from the station agent.”
